TLD 600-180-CUP

The TLD ASU‑600‑180‑CUP is a continuous-flow aircraft air start unit engineered for reliable ramp performance, delivering 180 lb/min (≈ 1.36 kg/s) of airflow at pressures up to 40 PSIG. Designed with rugged durability and advanced compressor and engine systems, this ASU efficiently supports modern regional and narrow-body aircraft operations.

Key Features:

“Oil-Free Dry-Screw Compressor – Durable rotary compressor designed to eliminate the need for coatings and minimize wear.

Dual Mode Operation – Supports both Air Packs and Jet Start modes, with independently adjustable supply pressures for enhanced adaptability. Automatic Throttle Roll-Back – Reduces engine speed when full output isn’t needed, lowering noise and fuel consumption.

Easy Access Canopy & Wide Doors – Simplifies routine maintenance with full component access.

Robust Chassis – Galvanized steel frame and powder-coated panels offer exceptional corrosion resistance.

Safety Systems – Integrated features protect against overpressure, high temperature, and low oil pressure. Control Instrumentation – Centralized engine and compressor monitoring panel for operational ease.

High-Temperature Output – Provides outlet air at approximately 210 °C (410 °F) to enable fast engine starts.

Extended Service Intervals – Compressor overhaul recommended at 25,000 operating hours.”
